OCIEnvInit() and heavy memmory leaks

Hi gentlemen,

here is a simplified piece of code for testing resource management :

1 - the allocation and de-allocation methods :

class COCIEnvironment {
bool COCIEnvironment::Initialize( BOOL bThreaded ) {
  m_initMode = bThreaded ? OCI_THREADED : OCI_DEFAULT;   m_initMode |= OCI_OBJECT;

  // Allocation of handle m_pEnv
::OCIEnvCreate( &m_pEnv, m_initMode, NULL, NULL, NULL, NULL, 0, NULL
);

  // Allocation of an error handle
::OCIHandleAlloc( m_pEnv, reinterpret_cast< void** >( &m_pErr ),
OCI_HTYPE_ERROR, 0, NULL );
  return true;
}

void COCIEnvironment::Terminate()
{
::OCIHandleFree( m_pErr, OCI_HTYPE_ERROR );
::OCITerminate( m_initMode );

  m_pEnv = NULL;
  m_pErr = NULL;
}
[...]
};

2 - the test code :
  COCIEnvironment env;
  cout << "Construction OCIEnvironment" << endl;

  for ( int i = 0; i < 20000; ++ i ) {
    env.Initialize();
    env.Terminate();
  }

While performing this loop, the system available memory dramatically falls. I loose some 700 Mo in a few seconds. Hence, I suspect heavy leaks in the above code, but I am definitely unable to find and explain them.

Have you some clues to help me ? Received on Mon Mar 13 2006 - 03:02:57 CST
